probably needs Drums of Doom recursion.
-Build an all organic castle! Become an ecoterrorist! Use Common Sense to search out answers or set up your defense. Use one to get ramp ie Landmass.
-Assorted Animals not only gets you a ton of little and efficient guys but it also thins your deck so you can draw what you really want to!
-Create walls around you and utilize the terrain to gain the edge.
---Pudge Butcher and Harpy can one shot enemies safely by utilizing Bottomless Pit or /Druid/Briar Patch + Drums of Doom combo.
---Bodach Bogeyman can pick up and drop off units to adjacent sites. Take'em to the Pit!
---Have a spider ruin their day by making them unable to do literally anything in two different ways! They dont have hobbits in this game yet, so you should be safe.
---Almost everything combos with Drums of Doom.
-Finishers include funny Wolpertinger guy, Gawr Gura and the Mid Army. Also epic Wyvern and Infiltrate.
-Poke from afar with Belmotte Longbowmen, Colicky Dragonettes and Midland Army. Or use Fail-not Bow to give 3 range to any Unit!
Sideboard:
-Drought, anti-water (duh)
-Boil, water (duh)
-Dispel. idk bro sometimes you really need it and sometimes you dont and it isnt consistent to affinity or avatar. I almost say leave 1 copy in all the time.
-The Kings bring in based on avatar.
-Dwarven Digging team against other earth so they dont just Cave-in your nature reserve.
I have no idea what to side out, trying to figure it out but cutting cards is hard.
If they bring battering ram, 1:why did they do that? 2:gg?
Can probably be improved but this is what I came up with. I will play in paper soon and report back. gl.
